What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.02056 |
| Opus 5.5 | $0.00045 | $0.00822 |
| Sonnet 5.5 | $0.00022 | $0.00411 |
| Haiku 4.5 | $0.00011 | $0.00206 |
Grade B, and why
security-audit scanned grade B with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Encoded or obfuscated payloadmediumSupply chain
base64 or hex that is decoded and executed hides what actually runs from anyone reading the file.
Base64/hex blobs, `eval(atob(...))`, hand-obfuscated strings = stop and dig. Subprocess/`create_subprocess_exec` hits: confirm they're `shell=False`, list-form args, and that no user-controlled value reaches the command. Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Flag: `pull_request_target` (especially with a checkout of PR code), newly referenced `secrets.*`, `curl|bash` / `wget|sh` to unknown hosts, Actions repinned to a fork or downgraded to a mutable tag, changed package regi Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security-audit is a skill published in the GitHub repository rommapp/romm (14,134 stars, last pushed today), licensed AGPL-3.0. It adds 112 tokens to every session and 2,056 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 3 findings (encoded or obfuscated payload, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
